If your Chrysler 300 has a dead battery, you can jump-start it safely by following these steps. The Chrysler 300 has its battery located in the trunk, but jump-starting can also be done using designated points under the hood. Here's a detailed guide to get your car running again.

Accessing the Vehicle and Battery

1. Unlock the vehicle manually:

- If the battery is completely dead, the key fob won't work. Remove the emergency key from the fob and use it to unlock the driver's door by turning it counterclockwise.

2. Pop the hood:

- Inside the car, locate the hood release lever near the driver’s side under the dashboard and pull it.

- Open the hood and find the secondary latch at the front of the car to lift and secure the hood.

3. Locate jump-start points:

- Under the hood, on the passenger side, you'll find a positive terminal (covered with a cap) and a negative ground point. These are designated for jump-starting if you don’t want to access the trunk battery.

4. Accessing the trunk battery (if needed):

- If you prefer to jump-start directly from the battery, fold down the rear seats by pulling their release loops, crawl into the trunk, and use the emergency release handle to open it.

- The battery is located under a panel in the trunk near the spare tire.

Connecting Jumper Cables

1. Prepare jumper cables:

- Use high-quality jumper cables or a jump box for better results.

2. Attach cables in this order:

- Connect one red clamp to your Chrysler 300’s positive terminal (under hood or trunk).

- Attach the other red clamp to the positive terminal of the donor battery.

- Connect one black clamp to the negative terminal of the donor battery.

- Attach the other black clamp to an unpainted metal surface on your Chrysler 300 (not directly on its negative terminal).

3. Safety tip: Ensure both vehicles are off before connecting cables.

Starting Your Vehicle

1. Start the donor vehicle and let it run for 5-10 minutes.

2. Attempt to start your Chrysler 300. If it doesn’t start immediately, wait another few minutes for more charge.

3. Once started, let your Chrysler 300 run for at least 15 minutes or drive it to recharge its battery.

Disconnecting Jumper Cables

1. Remove cables in reverse order:

- First, disconnect the black clamp from your Chrysler 300.

- Then disconnect the black clamp from the donor battery.

- Next, remove the red clamp from the donor battery.

- Finally, remove the red clamp from your Chrysler 300.

2. Replace any caps or covers on terminals and ensure all tools are removed.

Additional Tips

  • If jump-starting under the hood doesn’t work due to severe battery depletion, try connecting directly to the trunk battery.
  • If frequent jump-starts are needed, have your battery tested or replaced at a service center.
